SAFETY-PIN.

To all whom it may concern:

Be it known that I, ANNASTASIA COLLINS, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented'new and useful Improvements in Safety Plns, of

which the following is a specificationj This invention relates to a safety-pin.

It is the object of this invention to provide a pin which is particularly adapted for use in fastening dress shields to the underarm seams of shirtwaists and the like, and which is also applicable for use where it is desired to pin to curved seams, edges or surfaces without puckering or gathering the goods and consequently pulling it awry.

Another object is to provide a safety-pin which is so designed and constructed that the pin point will be completely closed and effectually guarded when fastened in its closed position, so as to prevent the point of the pin coming in contact with, or being engaged by, materials adjacent thereto.

A further object is to provide a keeper for insuring the pin remaining in its closed position and for preventing the pin being withdrawn therefrom by bending of the pinstem, thus obviating an objectionable feature commonly met with in most safetypins now generally in use; and to provide a safety-pin which will lie flat upon the surface to which it is attached.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a side elevation of the invention. Fig. 2 is an enlarged section on the line XX, Fig. 3. Fig. 3 is a plan view. Fig. 4 is a section and elevation on the line Y-Y, Fig. 1, in the direction indicated by the arrow a. Fig. 5 is an enlarged section and elevation on the line ZZ, Fig. 1, in the direction indicated by the arrow 6.

' In the drawings, A represents the back of the pin which is made of a resilient plate formed approximately in an arc of a circle and is bent downward at one of its terminals to form a loop or eye, which surrounds and engages a knob or head 2 on the end of a pin-stem 3. The pin-stem 3 is curved to substantially correspond to the curvature of the crowned back piece A and passes through a perforation 4 formed in the looped portion of the back piece A adjacent Specification of Letters Patent.

to its termination, as shown in Figs. 1 and 5; the pin-stem 3 normally extending at an acute angle in relation to the back piece A, as indicated in dotted lines in Fig. 1.

The outer end of the back piece A termi nates in an enlarged portion B, on the underside of the peripheral edge of which is formed a flange 4, which flange extends a short distance beneath the portion B and has a disk 5 mounted on its lower edge in such manner as to inclose the space surrounded by the flange 1'.

The flange 4 and the disk 5 form a cupshaped member which may be made in one piece, if desired, and soldered or otherwise attached to the underside of the portion B; the essential feature being to provide a hollow, substantially cylindrical-shaped member on the underside of the outer end of the back piece A. A portion of the flange 4 is removed to form a peripheral slot 6, which extends nearly half-way around the flange t on ,one side; this slot 6 being disposed adjacent to the underface of the portion B and of such width as to readily permit the insertion of the outer or pointed end of the pin-stem 3, the flange 4: being of such width that a portion of the flange material will extend between the slot 6 and the disk 5. One end of the slot 6 terminates at a point near the outer end of the portion B and the other end terminatesat a point beneath the center of the back piece A; the slot at this latter terminal turning at right angles and ending against the disk5to form a notch 7, as shown in Fig. 4:. The notch 7 is provided as ameans for engaging the pin-stem 3 when the outer end of the latter is inserted in the slot 6 to retain the pin in its closed position.

' In the application of this invention, the pin-stem 3 is passed through the materials to be pinned with its outer or pointed end extending a short distance therethrough. The back plate A is then given a sidewise movement so as to bring the slotted side of the flange 4 alongside of the outer end of the pin-stem 3, which pin is of suflicient length to extend nearly to the outer end of the slot 6. The pin-stem 3 is then inserted sidewise into the slot 6, whereupon, by reastem 3, the back plate A will be caused to spring back parallel with the pin-stem, so as to throw the pin in alinement with the notch 7 The pin then moves into the notch 7 by reason of the spring tension of resilient back plate A and is securely retained therein, this notch 7 preventing the outer end of the pin being moved outwardly through the slot 6 until the pin and back plate A are pressed and moved toward each other.

It will be observed that by mounting the pin-stem 3 on the back plate A, as here shown and described, there will be a pressure on the outer end of the pin 3 in two directions at the same time, one tending to retain the pin against the inner end of the slot 6 and the other tending to keep it against the end of the notch 7; thus effectually locking the pin against a too easy disengagement. It will also be observed that by reason of the pin-stem 3 being engaged at a point some distance from its outer end the thick ness of material pinned between the pinstem and the back A, which tends to spring the pin-stem away from the back A, is not likely to bend the pin-stem suiflciently far to withdraw its point out of engagement with the notched flange 4.

From the foregoing it is manifest .that when the pin-stem 3 is engaged in the notch 7 the point thereof will be effectually shielded and protected. By forming the back plate A and pin-stem 3 on a curve it is particularly adapted for use in pinning goods to curved scams or surfaces and by forming the back plate A of flat material, it will tend to lie in a fixed flat position when pinned tight on a seam. This pin is especially designed for use in attaching dress shields to the underarm seams of shirtwaists and the like, and by its lateral flatness and longitudinal curvature lends itself admirably to this purpose.

Having thus described my invention, what I claim and desire to secure by Letters Patent is A safety pin comprising a curved resilient back plate, a pin stem connected at one end to one end of said back plate, said pin stem extending in alinement with the longitudinal center of the back plate and having its opposite end pointed, the opposite end of said back plate terminating in an enlarged portion having an annular flange formed on the underside thereof, said flange having a plate mounted on its lower edge to inclose the.

space within the flange, and portions of said flange being removed to form a peripheral slot through which the outer end of the pin point may pass sidewise.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
